Palantir Cost Tuning

Overview

Optimize Foundry compute and API costs through incremental transforms, right-sized Spark profiles, efficient pagination, and usage monitoring.

Prerequisites

• Active Foundry enrollment with build history
• Access to Foundry resource usage metrics
• Understanding of transform build patterns

Instructions

Step 1: Cost Drivers in Foundry

Cost Category	Driver	Optimization
Compute	Full rebuilds of large transforms	Use @incremental()
Compute	Oversized Spark profiles	Right-size @configure profiles
Storage	Redundant dataset snapshots	Configure retention policies
API	High-frequency polling	Use webhooks instead
API	Small page sizes	Use max page_size (500)

Step 2: Convert Full Rebuilds to Incremental

from transforms.api import transform_df, Input, Output, incremental

# BEFORE: Full rebuild every run (expensive for large datasets)
@transform_df(Output("/out"), data=Input("/in"))
def expensive(data):
    return data.filter(data.status == "active")

# AFTER: Only processes new/changed rows
@incremental()
@transform_df(Output("/out"), data=Input("/in"))
def cheap(data):
     data.(data.status == )
